Wash cars or bikes if you have a big enough driveway. Gather some sponges or old rags, towels, car washing liquid, a big bucket, and a hose and set up a washing station in your driveway for a few hours on the weekend. Scrub each vehicle, focusing on any dirty spots, rinse it thoroughly, and buff it dry with a microfiber towel. Charge $10 to $20 per vehicle.
